Abstract
(English)
Owing to the variety of traffic profiles that Machine to Machine and Internet of Things applications may generate, this work studies the applicability of the Contention Resolution Diversity Slotted ALOHA (CRDSA) random access scheme, as in the DVB-RCS2 standard, when clusters of sensor nodes exchange data via satellite toward a sink via short-lived TCP/IP con- nections. In this scenario, uncorrelated sensor sources generate measurements, which are multiplexed by a satellite terminal, before being encapsulated and delivered through TCP/IP flows. This work aims at investigating the scalability in terms of number of concurrent satellite terminals, which can successfully transfer their own data with a small delivery delay in order to avoid congestion phenomena at MAC layers, which may induce collision storms. This work assesses the best practice for M2M elastic traffic wia random access satellite, investigating on cross- layer interactions between access layer and transport/application layers.
